    Installing Two Arresters in Parallel

    Everyone, Simply said ....what if adding only 30-40 USD to every arrester could be leading to already mentioned benefits (extended lifetime, increased robustness, improve protection level and uninterrupted protection)....specially in the following applications: 1) High Lightning Density Areas...

    Installing Two Arresters in Parallel

    Bacon4life, Yes, I completely agree with long leads on the photo and also with the possibility to address this so that can be as close as possible. In regards to already existing redundancy due to riser pole arresters + elbow type that could be true only to some extent cause the underground...

    Installing Two Arresters in Parallel

    Overall speaking benefits are as follows: 1) Increased robustness trough redundancy = higher reliability + resiliency 2) Decreases residual voltage , improving protection level 3) Eliminates no-protection window from an arrester failure all the way up to its changeout/ replacement. 4) Extends...

    Installing Two Arresters in Parallel

    jghrist Yes, Residual voltage in another benefit that can be acquired by putting 2 arresters due to the sharing current and charge transfer increased. If we see some specific application such as to protect underground cable and eqpt. it is desirable to have lower protection level (Vres) to...

    Installing Two Arresters in Parallel

    Cranky108, I understand what you mean ....but we´re not considering using 2 - 5kA arresters to 10 kA need but instead using 2 -10kA nominal current arresters to provide more robustness, that being said, those minor disparirites would produce a 70-30% for instance with the possibility to match...

    Installing Two Arresters in Parallel

    Bacon4life , Well, putting 2 arresters in parallel is related to the redundancy way to improve resiliency (more robustness due to increased current capability, 2 units with 10kA nominal current each) and adding to reliability taking into consideration that arresters are protection products...

    Installing Two Arresters in Parallel

    Hi everyone, wondering if some of you got experience or knowledge on the effectiveness or convenience of using 2 arresters in parallel..... Here i found this information related from a previous thread: thread238-160262 We are now considering the development of a DUAL ARRESTER ...there could...
